Question

How do you combine `(3x-7)/(3x+5) + (4x-3)/(3x+5)`?

Answer 1

`(7x-10)/(3x+5)`

Explanation:

Both of fractions have `3x+5` as the denominator, so you are able to just add the numerators without having to touch the denominator:

`(3x-7+4x-3)/(3x+5)`

Now you can combine like terms in the numerator:

`(7x-10)/(3x+5)` to get your answer.
